Gossen Metrawatt M360A – Peak Power Measuring Instrument and Curve Tracer

• Loop and line impedance measurement with DC bias magnetization
• Testing of RCCBs in IT systems
• Testing of insulation monitoring devices (IMDs)
• Testing of residual current monitoring devices (RCMs)

The PROFiTEST-PV permits the measurement of characteristic IU curves, as well as individual photovoltaic modules and strings.

With the help of a patented process, the instrument is capable of ascertaining peak power, internal series resistance and internal parallel resistance directly on-site “with only one measurement and without entering module data”, which are then indicated at a highßresolution color graphic touch-screen which is suitable for use in sunlight.

Troubleshooting in PV systems, as well as documentation of system quality, are executed quickly and economically during initial start-up and subsequent testing without a long learning curve.

This simple yet decisive test assures safety for the customer and eliminates consequential costs for the installer.

Measured peak power can, for example, also be used in order to determine peak ratio. Beyond this, acquired characteristic curves make it possible to draw further conclusions regarding the electrical characteristics of the measured module or string. And thus, the tester is also suitable for use in research and development.
